Post-micturition convulsion syndrome, I read, is a shiver felt along the spine, mostly in males, after urinating. For my life, I have had a post-micturition convulsion syndrome, but it isn't just a spine shiver, I find it to be almost violent "shivering," not quite full body, but more than just the extremities. How personal. So, what's up? Do I fit into this category, or is it something else?
